IMPROVEMENT IN NAIL-EXTRACTRS.

Specification forming part of Letters Patent No. 146,938, dat-ed January27, 1874; application filed February 4, 1873.

To all whom it may concern:

Be it known that 1, HORACE A. NETTLE- TON, of New Haven, in the countyof New Haven and State of Connecticut, have invented a new and ImprovedNaiLEXtractor; and that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, mak# ing apartot' this specification.

This invention relates to an improvement in an implement for extractingnails, &c.; and the invention consists in anail-puller consisting of alever hammer, tixed and adjustable jaws, and fulcrum, all constructedand operated in the manner hereinafter fully described.

In the accompanyin g sheet of drawings, Figure l represents a side viewof my invention; Fig. 2, a cross-section in the. line .r x; Fig. 3, across-section in the line y y.

Similarletters of reference indicate like parts in the several figures.

A represents a lever, which may be constructed of iron or otherdesirable material, and of any desired length. Into the upper edge ofthis lever a groove, a, is formed, extending from the grasp c nearly tothe Opposite end ofthe same. On one end of the lever A is castorotherwise formed a projection, b, with a flat surface, d, on its upperside, and to the end of the lever, and immediately below the projectionI), is rmlysecure-d aiXed claw, C. This claw is made of steel, andprojects below the end of the lever, as shown in Fig. 1, and, secured tothe said end, is affixed a second claw, D, in such manner as to enablethe points of the respective claws to be brought nearly in the sameline. The claw D is secured to the lever, so that it' may freely turn ormove to. or from the fixed claw C, and its outer side is prolonged intoa curved fulcrum, E. Pivoted to the lever A, at or near one end of thegroove or slot a, is a stem or guide, F, which may be made fromwrought-iron or other suitable metal. This stem is of such dimensions aswill allow it to fit snugly within the slot a,

and it extends nearly up to the projection b, where it terminates in asolid head, G, immediately over and resting upon the iiat surface d ofthe projection b.

The construction of my implement being substantially as above described,its operation is as follows: The lever A is held in such position aswill bring the points of the claws and D immediately over the head of anail it is desired to draw; and then the head G is raised (the pivotedend of the stem F acting as a hinge) and brought, with one or moreblows, in contact with the flat surface el ot' the projection b, whenthe concussive force will drive the points of' the claws into the woodsurrounding the nail-head. The end ot' the lever A is raised, bringingthe fulcrum E in contact with the surface dof'the box within which thenail is driven, and forcing the point of the claw D tightly against thenailhead, which is thus jammed between said movable claw and the fixedclaw C, and as the lever A is raised the nail is withdrawn. The fulcruniE yielding as the nail is withdrawn permits the nail to be drawn withoutbending it, ready to be driven again, if necessary. The fulcruni E iskept in its normal position by the spring From the foregoing descriptionof the construction and operation of my implement, it will readily beseen that with it a nail may bc withdrawn from the wood within which itis embedded, in an expeditious manner, (even though its head may becountersunk below the surfaee,) without injury to the wood within whichit is driven or to the nail.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A nail-puller constructed of the leverA, stem. F, xed and adjustableclaws C and D, fulcrum E, and hammer G, as and for the purpose dcscribed.
